	Howcomyoucom.com The Earliest Known Relative Of Marsupial Mammals
		Prior to the discovery of Sinodelphys, the previously earliest metatherian fossils were some isolated teeth from the 110 million year old sediments of North America.
		A nearly complete skeleton of Sinodelphys, preserved on a shale slab, was found in the Mesozoic Yixian Formation in western Liaoning Province of China.
		As with modern tree-dwelling animals, Sinodelphys' shoulder, limbs and feet suggest that it was quite capable of climbing.

	Sinodelphys szalayi - CMNH (Site not responding. Last check: 2007-10-21)
		All living mammals are divided into three groups primarily based on their reproductive systems: monotremes (those who lay eggs), placentals (those who give birth to live and more mature young), and marsupials (those who give birth to live, less mature young that they then nurse in their pouches).
		Modern marsupials are a significant part of the larger metatherian mammal group, and are the descendants of the extinct metatherians that lived during the Age of Dinosaurs, known as the Mesozoic.
		Sinodelphys was one of several mammals in the Yixian biota, including the earliest-known placental relative, Eomaia, the symmetrodonts Zhangheotherium and Maotherium, the eutriconodonts Jeholodens and Repenomamus, and the multituberculate Sinobaatar.

	Science spotlights oldest known marsupial - PittsburghLIVE.com
		Sinodelphys is the earliest known marsupial, according to Science magazine
		Liaoning, whose terrain is dotted with shale quarries, has yielded a treasure trove of spectacularly preserved fossils, including feathered dinosaurs known as theropods; the earliest known relative of the flowering plant, archaeofructus; and eomaia scansoria, the oldest known placental mammal.
		The team determined that Sinodelphys was related to the marsupials by analyzing the bone structure in its wrist and ankles, said Luo, who lives in Franklin Park.

	MSN Encarta - Print Preview - Marsupial
		A fossil found in China is thought to be an early ancestor of marsupials and dates from 125 million years ago.
		Called Sinodelphys, it was about the size of a chipmunk and climbed trees.
		This primitive marsupial shares many features with living marsupials and suggests that marsupials may have originated in Asia, spread to North America, and later migrated to present-day South America.

		The near-complete skeleton of Sinodelphys is strikingly well preserved, with tufts of fur and even soft tissues imprinted on the slate slab in which it was found.
		"[Sinodelphys] increases our appreciation for the antiquity of this great and fascinating group of mammals, and makes those of us who have obsessions about pouches proud to be so afflicted," said Archer.

		The 125-million-year-old relative of today's marsupial mammals, dubbed Sinodelphys szalayi, likely lived in bushes or the lower branches of trees, where it could hide from dinosaurs and other predators while munching on insects.
		Marsupial mammals are born at an early stage and carried in a pouch on their mother's abdomen until fully developed.
		The Sinodelphys skeleton, found in the same famed fossil quarry that has yielded remains of feathered dinosaurs, was preserved on a shale slab and is nearly complete.

		A near complete skeletal fossil of the chipmunk-size, marsupial ancestor Sinodelphys szalayi has been dug up from 125-million-year-old shales in China's northeastern Liaoning province.
		Sinodelphys, which shares more wrist, ankle and dental features with living marsupials than other mammals, will help researchers understand what the ancestor to all marsupials may have been like.
		The fossil will also help scientists piece together the early history of all placental and marsupial mammals, according to the Chinese and American paleontologists who detail their analysis of the fossil in the current edition of the research journal Science.

		The authors claim the discovery of Sinodelphys supports theories that the ancestors of marsupials diverged from the ancestors of placental mammals in Asia.
		In 2002, Luo and colleagues described the earliest fossil placental mammal - Eomaia scansoria - which was discovered in the same quarry in northeastern China as Sinodelphys.

		If you were Sinodelphys, the one joined to the rest of the hand would represent a metacarpal.
		In Sinodelphys, (flicking back to p.1935): "Its lower molars have developed an approximation of the entoconid to the hypoconulid..." Interestingly, the authors also observe that: "the entoconid is indistinct or absent..." in some of the generally further derived deltatheroidans.

		Dec 12, 9:32 am ET WASHINGTON (Reuters) - A 125 million-year-old fossil found in northeast China is probably the oldest known ancestor of modern marsupials, U.S. and Chinese researchers said on Thursday.
		The furry mouse-sized creature, named Sinodelphys szalayi, would have climbed trees, they report in this week's issue of the journal Science.
		The fossil is 50 million years older than the oldest known marsupial fossil to date and the finding sheds light on when marsupials diverged from placental mammals -- which include humans, cats and dogs.

		The surprisingly complete skeleton of the mouse-sized creature, Sinodelphys szalayi, has been dated to 125 million years ago, according to its American and Chinese discoverers.
		This is 50 million years older than the previous oldest marsupial skeleton, and sheds doubt on the prevailing theory that marsupials originated in North America.

		The newly discovered fossil mammal, Sinodelphys szalayi (found in the Liaoning Province in northeast China) allegedly lived during the early Cretaceous period (144-65 million years ago).
		As it turns out, researchers are unable to use the teeth of Sinodelphy szalayi to help them sort out this puzzle, and, in fact, the teeth do not even tell them much about the environment in which this creature lived.
		As evinced by this discovery of Sinodelphy szalayi, geographic separation cannot be as significant to the marsupials’ development as evolutionists posit.

		Luo noted that Sinodelphys had hands and feet with fingers and strong wrists well adapted to climbing, indicating it could retreat to the trees to avoid hunting dinosaurs.
		The discovery also adds support for the 19th century theory of Thomas Henry Huxley that the first marsupials lived in trees.

		Its wrist and ankle bones, and some of its teeth, suggest it was a primitive marsupial, the group of mammals that raise their young in external pouches and includes kangaroos, wombats, bandicoots and opossums.
		This one, called Sinodelphys szalayi, probably lived in bushy vegetation near fresh water.
		It probably ate insects and worms and had a body suited to climbing the lower branches of trees and shrubs, the report said.

	New Scientist Breaking News - Earliest known marsupial unearthed in China
		China's Yixian rock formation, which is 125 million years old, has produced a spectacular haul of early mammal fossils, including, in 2002, the earliest known placental mammal, Eomaia scansoria.
		The discovery of the 125 million-year-old Sinodelphys szalayi fits in with what has been suggested about the timing of mammal diversification, although it is still not known exactly when the two main lineages arose.
		But since the earliest marsupial and placental remains, along with slightly younger relatives, have been found in China, "we argue that Eurasia is the main continent where the earliest split of the placental and marsupial lineages occurred," Luo told New Scientist.

		Scientists searching an ancient volcanic deposit in China have unearthed the skeleton of the oldest marsupial yet found, a furry, long-tailed, mouse-sized creature that ate insects and probably climbed trees to escape hungry dinosaurs.
		The discovery of Sinodelphys szalayi@ in the 125 million-year-old fossil beds of China's northeastern Liaoning province has deepened the mystery surrounding the origins, dispersion and fate of marsupials--pouched mammals represented today mostly by opossums and Australian species like kangaroos, koala bears and wombats.
		The find also suggests that the divergence between marsupials, whose females nurture their babies inside a pouch, and placental mammals, whose young mature inside the mother, occurred earlier than once thought.
